[Zope] Newbee- Import file

Hi it's me again, I had a look on the FileLibrary and it's functionality to import a file is quit close to that what I got in mind ... but unfortunately only close, not exactly: I my situation I got a dynamically created pdf File (via mysql/cocoon). All I want is to save this dynamically created file somewhere on the server (it is the same for cocoon and Zope) or better save the generated pdf File directly to the Zope File Library. But how could I do it ? I do not want to save the pdf first on my local system and do from there the import to Zope, like it is possible with the simple form <import file .... >. Thanks in advance J.
